PTQuerySchemaVersionSupport function

Retrieves the highest (latest) version of the Print Schema that the specified printer supports.

Syntax


HRESULT PTQuerySchemaVersionSupport(
  _In_   PCWSTR pszPrinterName,
  _Out_  DWORD *pMaxVersion
);

Parameters

pszPrinterName [in]

A pointer to the full name of a print queue.

pMaxVersion [out]

A pointer to the highest version.

Return value

If the operation succeeds, the return value is S_OK, otherwise the HRESULT contains an error code.

For more information about COM error codes, see Error Handling.

Remarks

Note  This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation—factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.

The pszPrinterName parameter must be the full name, not the truncated name as it may appear in a DEVMODE.

The first version of the Print Schema was released with Windows Vista and is version 1.
